I have a 2000 VW GTI VR6.I'm trying to connect a performince chip

I have a 2000 VW GTI VR6. I'm trying to connect a performance chip to my intake air temp sensor. I think it is part of the mass air flow sensor. It has five wires. #1 blue with yellow strip. #2 small wire red with purple. #3 small wire purple with green. #4 and #5 are wrapped together, green and black. I cant find the right one to connect to. If both sensors are one! my last 6 # of vin- 672708

Do not cut into these wires. any real performance programmer will not require you to do this. these ones that tell you to cut into the IAT will ruin a $700 mass air flow meter, and do not do anything. all they do is try to trick the computer into thinking it is colder then it actually is, and to richen the fuel mixture, which will actually HURT performance and emissions because the air density does not match what the temp sensor is reading. the temp sensor is there for a reason!

Find the purge valve (pictured below) by tracing vacuum hoses that are connected to the intake manifold. It will be connected to one of those hoses. Might be on the firewall. If you don't find it, maybe the hose is disconnected from the manifold. Look for an open vacuum port on the manifold that SHOULD connect to the purge valve.

When you opened the bleeder screws to the rear brakes, did you completely remove the screws ? Might also want to perform a complete visual inspection of the brake lines from the rear to the front and master cylinder.
How are you performing the bleeding process ?

could possibly be a faulty latch. door latch, trunk latch, hood latch. something sporadically not recognizing a closed latch to cause it to go off sporadically. a scan with a vw scan tool or a vag com should detect a fault in the convenience system.
